If you’re looking for your next powerful crate engine for your restomod, check out the new LS427/570 from Chevrolet Performance, it might just be a perfect choice. This powerful mill is built on the track-bred performance of the LS7 engine but enhances that platform in two important ways: it delivers more power and offers easier installation. Inside, you will find a new, higher-lift camshaft that helps it produce 570 horsepower and 540 lb.-ft. of torque. That is an increase of 65hp and 70lb.-ft. over the production-based LS7 crate engine.
As mentioned, the key to helping make this the most powerful naturally aspirated LS crate engine in Chevy Performance’s catalog is the new high-lift hydraulic-roller camshaft. However, redesigned internals, low-profile intake manifold, new high-rate valve springs, CNC-ported cylinder heads, titanium intake valves, sodium-filled exhaust valves, titanium connecting rods, and a 14-inch transmission flywheel from the fifth-generation Camaro Z/28 all add to the engine’s performance prowess. The Camaro Z/28 also donates its exhaust manifolds, replacing those previously gleaned from the Corvette Z06.
LS swaps can be time-consuming, but GM has made the process even simpler by offering this crate with a wet-sump oiling system. This eliminates the need to swap the oil system or the need to make room for a separate oil tank and oil lines to make it work. There’s now an oil pan from GM’s F-body cars feeding a specific wet-sump oil pump.
GM didn’t reveal a price on the SEMA 360 website, but the 505-hp LS7 pricing starts at around $11,000 from some retailers, so start thinking upward from there. The LS427/570 needs a dedicated LS427/570 engine controller, so factor that cost in, too.
LS swaps have taken over the world, and Chevrolet Performance is making sure they can deliver the power you need.
